Wiper Blade Drum Xerox Workcentre 7220 / 7225

Component Construction. Under a standard design, the wiper blade is attached to the OPC Drum laterally. The component may be stationary but it creates friction against the drums surface as the OPC Drum rotates at high speed. Nonetheless, only a sufficient amount of pressure that corresponds to necessary function is applied on the drums surface to rid it of excess toner after every print cycle. MFPBS wiper blade provide the right pressure to the OPC. Undue pressure can speed up the deterioration of the sensitive drums surface which would consequently affect the tolerances required to prevent print defects.
